Omikron Posted March 29, 2012 Posted March 29, 2012 Hello Everyone This is my entry for "To sail a Technic sea" contest. Video is SORRY FOR TERRIBLE quality, I'll get better camera tomorrow and will make a new one Quick overview and some info: Weight about 4,3 kg Parts count: more than 4800 Has 2 arms - pneumatic sample arm and heavy duty arm Uses 4 M motors and 1 XL motor Uses 3 battery boxes 1 Additional M motor is used to power the heavy duty arm Has 2 gearboxes - main (the big red one) for operating arms functions secondary gearbox for operating propellers, tail stabilizer and retracting lights Has 2 tail (upper and lower) propulsion distributors and 1 front propulsion distributor. 1 Pilot seat Length 76cm Width 50 cm Hight 30 cm (without the tail stabilizer) The whole construction is using a stand, mainly because of the lower gearing system, axles and weight Functions: 1.The hull has pneumatically opening/closing hatch 2. 2 independent light sources 3. Retracting lights 4. Diving rudders pneumatically controlled from the pilot joystick 5. "Rising" tail stabilizer 6. The "X12" engine. 7. 8 propellers (4 propulsion ,2 vertical, 2 horizontal) driven at the same time from the XL motor (I was trying to make third gearbox for switching between propellers but I ran out of parts and didn't receive new parts yet, I will make this gearbox later) 8. 2 Counter opposite pneumatic pumps running at the same time (when the first pump is recharging the second provides airflow) providing constant airflow 9. Remote controlled switching of gears 10.Remote controlled Left and Right arms 11. 360 degrees rotation of right arm 12. Abduction/adduction of right arm 13. Elevating main boom of right arm 14. Elevating secondary boom of right arm 15. Heavy duty instrument driven by 1 additional M motor (this one is like the Unimog, I'll make lots of different instruments like saws, cutters, drills and other) 16. 360 degrees rotation of the left arm 17. Pneumatically controlled main boom 18. Pneumatically controlled secondary boom 19. Left arm pneumatic grabber. (The left arm can operate between 2 baskets (the lower one sample basket and the left upper one) 20. Abduction/adduction of the left arm. All Arms functions could be controlled in the adducted, during abducting and adducted positions. Functions 6,7,8 are driven at the same time from XL motor with additional possibility of powering function #3 or #5 Gearboxes: 1. Main Big red one gearbox is used to power and switch between arms. 2. Secondary tail gearbox is manually controlled and is used to control retraction of the lights and for controlling the "underwater" and "surface" mods of the submarine. The undone: I've ordered most of the parts in February and didn't receive the main package with my new shiny hull parts. The hull supposed to be in different color and shape, but without this package I made what I could. This creation is my first since "dark ages" I believe I didn't hold Lego parts for more than 10 years. I hope I will be able to create more. Oh and I have some photos of building process, some features, prototypes I used in this entry, if anyone is interested - just ask and will post it. Sorry for mistakes and bad English.
Lipko Posted March 29, 2012 Posted March 29, 2012 We have the winner? That is awesome. One little complaint though (which is probably not intentional): the inconsistent colors.
efferman Posted March 29, 2012 Posted March 29, 2012 We have the winner? we will seethe leviathan is impressive, but we have many impressive entrys in the contest
Technic Gearhead Posted March 29, 2012 Posted March 29, 2012 Ding ding, we have a winner! Pretty impressive looking entry.
Edwin Korstanje Posted March 29, 2012 Posted March 29, 2012 Very great MOC , but for the winner he haved too many colors jused .
timslegos Posted March 29, 2012 Posted March 29, 2012 wow that is quite a MOC. nice job coordinating all the functions. tim
DLuders Posted March 29, 2012 Posted March 29, 2012 Wow! Didn't James Cameron (of "Titanic" fame) use one of these last week to dive to the deepest part of the ocean?
legobodgers Posted March 30, 2012 Posted March 30, 2012 Beautiful model, have fun building your Unimog.
TinkerBrick Posted March 30, 2012 Posted March 30, 2012 @ OmiKron Great MOC and entry for the competition. Loads of functions. I especially like the look of the cockpit, one could think there would be an acrylic glass sphere. Although one feature doesn't make sense to me at all - the V6 engine one the bottom. Such exploration vessels use batteries or if more advanced fuel cells, since it's hard to get the required air in such depths. You could have left the engine out and added a small battery box in that place. That would make it appear more realistic. I'd love to see it shrink wrapped/sealed water tight (if this would be possible be any means) and see it working under water. Note to myself: Suggest watertight PowerFunctions on Cussoo Anyway - mind blowing Vessel.
Omikron Posted March 30, 2012 Author Posted March 30, 2012 (edited) Thank you all for the replies. I thought about engine problem TinkerBrick before I added it to the submarine. It is not a v6 - it is X12. And it is not diesel or oil or petrol engine. I prefer to think that it uses hydrogen and oxygen from surrounding water. The submarine carries some battery (like the car) to start the synthesis of hydrogen and oxygen from water by electrolysis. Then Hydrogen is used as power source and is burnt (hydrogen + oxygen = combustion) inside the engine providing it's chemical energy. The engine is rotating the generator to make more electric energy which could be stored or used. The efficiency of this engine type is about 50-80%. Could power the whole submarine for a very long time Why not, when you are floating in the fuel. Edited March 30, 2012 by Omikron

Good looking engine, but you do realise, that it takes exactly the same amount of energy to electrolyse the water that you can earn from it with burning (The energy you get from burning H and O all goes to electrolyse the water). Taking the energy loss into account, you end up with a less efficient system (with more batteries and gas storing devices) than simply having the batteries power the electric motors directly. Of course, you could use compressed and stored O and H to power the engine. Edited March 30, 2012 by Lipko

dhc6twinotter Posted March 30, 2012 Posted March 30, 2012 (edited) Nice looking moc! Lots of nice functions there. Do you have any pictures of the internal gearing, etc? I think you're at the picture limit in this thread, but if you have a brickshelf or flickr account, please post a link. More pictures would be great! What does the wire connector hanging out of the yellow arm do? Is that for future attachments? I love this contest. So many people have uploaded great entries! This is going to be difficult to judge.

I have some pictures of early building process, some prototypes and so on. The Wire is for controlling the heavy arm's "device". I've got one of the last packages today with extension wires so I'll post photo and video a bit later Edited March 30, 2012 by Omikron
Omikron Posted March 31, 2012 Author Posted March 31, 2012 Good news Everyone! I've created brickshelf account and posted some additional photos! Also made a new video of arms functions (no new camera , sorry) Don't know am I allowed to post 2 videos though. If I'm not then I'll delete one of them immediately. New video is
DLuders Posted March 31, 2012 Posted March 31, 2012 @ Omikron: Very impressive MOC! Since your Brickshelf folder is not yet "public", nobody except yourself can see your images. It may be several days before the Bricklink moderator makes your folder public. However, you can "deeplink" your images using the procedures here so that people can see them now.
Omikron Posted March 31, 2012 Author Posted March 31, 2012 (edited) Here are some photos of building progress. All photos were resized to 800x600 but you can see them in higher resolution in my brickshelf gallery here Early gearbox prototype Pilot's seat (the pilot can walk down the shaft after the hatch is opened) Twin pneumatic system (providing constant airflow) Stand Diving control Pneumatic control Heavy duty arm's control Heavy arm's chainbox No outer frame Arms adduction mechanics Early arms build Early arms + main gearbox Installed engine Installed secondary gearbox Early pneumatic concept (was changed because of weight balancing and huge empty space in left arm section) Edited April 5, 2012 by Omikron
laix Posted March 31, 2012 Posted March 31, 2012 I love your model, it's pretty awesome to see such huge models in action and the looks of it are awesome.
Omikron Posted April 3, 2012 Author Posted April 3, 2012 I've finally finished the new hull Wait for the tomorrow update. More info and pics are incoming Maybe a new vid
Siegfried Posted April 3, 2012 Posted April 3, 2012 Caution! Some of them are pretty big, so they will be under spoiler This achieves nothing. The image is still loaded regardless. Please just don't post big images. Any topics with oversized images either be invalid or have the images removed, depending on my grumpiness on the day. The rules are there for a reason, don't try to outsmart them. Don't know am I allowed to post 2 videos though. If I'm not then I'll delete one of them immediately. You're not. But like most you'll need to make a new topic anyway as this one has too many images. (You can link to this one in the topic though. )

I've edited post and will upload small photos tomorrow.
LEGO Train 12 Volts Posted April 3, 2012 Posted April 3, 2012 This is too much for me ...this is an absolute masterpiece!
